Question

(a+b)^2- 4b(a+c)+4b^2 simplify​

Answer 1

Answer:

a² + 5b² -2ab -4ac

Step-by-step explanation:

( a + b )² - 4b (a+ c ) + 4b²

let's open the bracket first

a² + b² + 2ab - 4ab - 4bc + 4b²

then we will simplify it

a² + ( b² + 4 b² ) + ( 2ab -4ab ) -4ac ⇒a² + 5b² -2ab -4ac

this is the simplest form of the given equation
